小男孩班上即將舉辦田徑比賽，大家在比賽當天表現如何呢？又會發生什麼有趣的事呢？ Black Lagoon系列故事都是在描寫小男孩在學校所碰到的老師、校長、護士、、、等等時，在真正看到這些人物前，他心中的假想情形，可以看到小朋友內心深處的想法。也可以看到小朋友天馬行空般的想像力。適合5歲以上兒童閱讀。
There's just one week until field day at the Black Lagoon and Hubie is going to be ready!
But getting in shape in one week is harder than he thinks -- especially when the workout kit he has seems to be for chickens. Why else would he be developing his pecs and thighs?
When the two teams finally meet on the big day, there's more than winning at stake. Will their friendships survive the cut-throat water balloon tosses and three-legged races that await them?
